        SJTU Research Team Won IEEE ComSoc Asia-Pacific Outstanding Paper Award

        December 12, 2019      Author:

        On December 9 to 13, Prof. Xia Bin from SJTU  School of Electronic Engineering, Associate Researcher Chen Zhiyong from Cooperative Medianet Innovation Center, and Doctoral Student Yang Chenchen from the Department of Electronic Engineering won the 8th IEEE ComSoc Asia-Pacific  at GLOBECOM in Hawaii.

        The IEEE ComSoc Asia-Pacific Outstanding Paper Award was established in 2012, which aims to award a publication of an original paper in any Communications Society magazine and journal in the previous 3 calendar years. This year, three papers were awarded at GLOBECOM.

        The award-winning paper Analysis on Cache‐Enabled Wireless Heterogeneous Networks demonstrates a theoretical guidance to optimal allocation of 3D resources in mobile computing communication network.

        The paper was published on January 2016 on the volume 15 of IEEE Transactions on Wireless Communications. Doctor Yao Yao from Huawei was one of the co-authors. According to ESI, the paper has also been the highly cited paper for three consecutive years since 2017, which means it ranks in the top 1% by citations in specific field in 10 years. So far, it has received 227 citations from Google Scholar.

        This paper was funded by the National 863 Plan and 5G Key Program, the Youth Foundation of National Science and Natural Foundation of China and other foundations.



        Caching popular multimedia content is a promising way to unleash the ultimate potential of wireless networks. In this paper, we propose and analyze cache-based content delivery in a three-tier heterogeneous network (HetNet), where base stations (BSs), relays, and device-to-device (D2D) pairs are included. We advocate proactively caching popular content in the relays and parts of the users with caching ability when the network is off-peak. The cached content can be reused for frequent access to offload the cellular network traffic. The node locations are first modeled as mutually independent Poisson point processes (PPPs) and the corresponding content access protocol is developed. The average ergodic rate and outage probability in the downlink are then analyzed theoretically. We further derive the throughput and the delay based on the multiclass processor-sharing queue model and the continuous-time Markov process. According to the critical condition of the steady state in the HetNet, the maximum traffic load and the global throughput gain are investigated. Moreover, impacts of some key network characteristics, e.g., the heterogeneity of multimedia contents, node densities, and the limited caching capacities, on the system performance are elaborated on to provide valuable insight.
